Brown eye-color is dominant while the blue-eye color is recessive. Therefore, the homozygous for brown color is BB and the homozygous for brown color is bb. Thus, the heterozygous will be Bb (brown color). Since James has blue colored eyes a child of Jenna (brown color) and bill (blue color) then it means Jenna is heterozygous (Bb). Jenna is described as being a carrier of the allele for blue eyes.
A hereditary characteristic, brachydactyly type D shows autosomal predominance and is regularly created or acquired freely of other genetic qualities. The condition is related to the HOXD13 quality, which is main in digital formation and development.

Brachydactyly
Brachydactyly is a shortening of the fingers and toes because of curiously short bones. This is an acquired condition, and much of the time does not present any issues for the individual who has it. There are various kinds of brachydactyly, in view of which bones are abbreviated. This condition can likewise be a side effect of another hereditary issue. Except if there is a going with confusion that produces side effects, or the abbreviated digits weaken the utilization of hands and feet, there is no treatment required for brachydactyly. Most common type of brachydactyly is d type. In this type end bones of the thumbs are shortened.
Symptoms
The indications of brachydactyly are generally present during childbirth, however, it's conceivable that abbreviated appendages become increasingly evident with development and advancement. The fundamental symptoms of brachydactyly are fingers, toes, or both that are shorter than typical. Surgery is the only solution for this.
Reasons behind brachydactyly
It is an autosomal dominant disorder, which means you just need one parent with the quality to acquire the condition. It's idea that two distinct transformations in a specific quality add to brachydactyly. Now and again, it's conceivable that brachydactyly is brought about by medicines that the mother takes during pregnancy. It might likewise be brought about by bloodstream issues to the hand and feet, particularly in newborns. Brachydactyly D is symptomatic of a hereditary disorder. This may be due to incomplete dominance.

Answer:
11)El ciclo del agua, conocido científicamente como ciclo hidrológico, se refiere al intercambio continuo de agua en la hidrosfera, entre la atmósfera, el agua del suelo, la superficie, el agua subterránea y las plantas. La ciencia que estudia el ciclo hidrológico es la hidrología.
12)Sabems que las etapas del ciclo hidrológico son las siguientes:
Evaporación
Condensación
Precipitación.
Las implicaciones que tienen para la vida cada una de las etapas son:
Evaporación, se reduce el nivel de los ríos, los lagos pequeños se seca, y se eleva la temperatura del ambiente.
Condensación, Es el proceso en el cual se forman las nubes, por lo que la luz solar disminuye.
Precipitación, produce nuevamente el aumento de los niveles de rios y lagos, y la disminución de la temperatura.
